Chapter 3.2
Energy changes forms
Using Energy Conversions
Conversions Between Potential Energy and Kinetic Energy
Energy is always conserved
The law of conservation of energy states that energy can neither be created nor destoryed
Energy conversations may produce unwanted forms of energy
Energy efficiency is a measurement of usable after an energy conversion
Chapter 3.1
Different forms of energy have different uses
Energy
Energy is the ability to cause change
Forms of Energy
Mechanical Energy
The energy that moves objects
Sound Energy
Sound results from the vibration of particles in a solid, liquids, or gas
Chemical Energy
Energy that is stored in the chemical composition of matter
Thermal Energy
The total amount of energy from the movement of particles in matter
Electromagnetic Energy
Transmitted through space in the form of electromagnetic waves
Also r
Nuclear Energy
The center of an atom-its nucleus-is the source of nuclear energy
Kinetic energy and potential energy are the two general types of energy
Kinetic Energy
Kinetic energy is the energy of motion
Kinetic energy increases as mass increases
Kinetic energy increases as speed increases
Potential energy
Potential energy is the stored energy that an object has due to its position of chemical composition
Chapter 3.3
Technology improves energy converstions
Efficient Lights
Efficient Cars
Technology improves the use of energy resources
Solar Energy
Solar cells are made of several layers of light-sensitive materials, which convert sunlight directly into electrical energy
Wind Energy
